boomerang, a MATLAB code which considers the boomerang tiling puzzle, a smaller version of the eternity puzzle. The puzzle specifies a region R composed of 2376 30-60-90 triangles, and a set of 66 "tiles", each consisting of 36 30-60-90 triangles, and seeks an arrangement of the tiles that exactly covers the region.
cplex, examples which call cplex(), which is an IBM optimization package which defines and solves a variety of linear programming problems, as well as network flow problems, quadratic programming problems, and mixed integer programming problems.
